forget using the stock harness for a + connection on your aftermarket stereo, when you turn it up loud, it'll make your dash dim. easiest cure: get some 12ga wire and run it with an inline fuse straight from your battrey to the unit. dont forget to unhook your neg. cable before doing any work. also, the hanes manual has wire diagrms and there are some websites outhere that have wire color charts for most modern vehichles, do a search.
and yes sloth, it is hot. or you can turn the ignition off and touch all loose wires to ground till one zaps and you toast your fuse. then connect that one and replace the fuse. i dont reccommend this method, but it works.
